I just plugged in a photon for what I think was the first time (this one was a gift and I hadn’t used it yet). I have a couple others that work fine. The particle looked like it set up properly, but the app said it was offline and couldn’t finish. The particle was breathing cyan but D7 is always dimly lit. I tried tying D7 to ground as someone suggested and I also tried resetting wifi and safe mode and DFU mode. I am not able to enter safe mode and in DFU mode, the command line says no DFU device found even though its blinking yellow (with D7 still on).
Any ideas on whats going on? How do I fix this?
